'lhis invention relates to improvements in strip folding and feeding mechanism, and with reference to more particular features thereof, it relates to improvements in folding and feeding mechanism for the record strips of writing machines such for example, as autographic registers.

It is the general object of the invention to provide, in a machine of the class mentioned,

an improved record strip feeding and folding a mechanism including a simple arrangement whereby apertures formed inthe strips are utilized for deflecting a record strip toward folded position in a zigzag folded pad.

A further and more particular object of the invention is to provide, in a machineof the class mentioned, an improved record strip feeding and folding mechanism wherein apertures provided in the strip for controlling the feed thereof may be also utilized for folding the strip neatly into a zigzag folded pad.

Still another object of the'invention is to 1 provide, in a machine of the class mentioned,

an improved strip folding mechanism for record strips having a longitudinal series of feed controllingapertures and being adapted to coaet, in its folding cooperation with the strip, only with the alternate successive feed controlling apertures, and functioning to defleet certain predetermined parts of the strip at one end of a zigzag folded storage pack or pad which may be housed within the machine and protected against unauthorized access.

A further object is to provide, in a machine of the class mentioned, record strip feed discs which are modified in such a manner as to cooperate with a record strip to deflect successivc parts thereof into folded condition.

Another object of the invention is to provide an improved record strip folding mechanism automatically controlled by strip feeding mechanism to selectively deflect certain parts of the strip into folded condition.

Other objects of the invention will he in part pointed out in the following detailed description of an illustrative but preferred emhodiment of the invention, and will be in part till Rig. 1 is a vertical transverse section through the record strip feeding and folding mechanism of an autographic register embodying the features of the invention;

Fig. 6 is a plan. of the record strips arranged in superposed. relation and constructed for use in the improved machine.

Referring more particularly to the drawing for a detailed description of the illustrative form of the invention, the novel features of construction thereof are there shown 11 as embodied in a machine of the autographic 'may be of any desire hown form, but for convenience in handling and satisfactory use in operation, the zigzag type of supply pad is preferred in which a plurality of record strips A are arranged in superposed relation and inter-folded zigzag. The strips A are led from this supply pad over appropriate guiding mechanism to the platen 12 of the machine u on which it is supported for man'i fold inscription. lit will he understood that a cover plate l2 may overlie this platen and carbon or transfer sheets may he supported in position for interleaving with the record strips over the platen.

At the forward part of the machine, a coinpartment 13 is provided in the casing in which one or more of the record strips may be refolded zigzag in a compact pad B and retained in this compartment from unauthorized access. For this purpose, the compart- All tit

ment may be provided with a closure (not An improved feeding and folding mechanism is provided for feeding the record strips forwardly from thesupply pad into inscription receiving position over the platen, this feeding mechanism being preferably located intermediate the length of the machine adjacent to and partially overlying the refolded or storage compartment. This feeding and folding mechanism is arranged to align the strips with each other and with the platen and to refold one or more of the strips, as more fully described below.

The form of record strip especially adapted for use in the improved machine is shown in Fig. 6 in which three-strips are shown arranged in superposed relation but a greater or smaller number may be utilized. As shown, it is preferred that each strip be formed with transverse weakened lines let which may be in the form of cuts or perforations which decrease the resistance of the strip to folding thereof and also provide severance lines along which the'recordedportions of the strip may be severed. The transverseweakened lines are spaced apart 1ongitudinally of the strips so as to lie substan tially at the ends of the zigzag pack when in folded condition, the strips being ordinarily folded at said lines and the consecutive folds being oppositely directed as shown in Fi 2. When the strips are refolded the refol ing tendency engendered by these weakened fold lines will aid in refolding the strip provided, of course, the strip is refolded in the same direction. The spaces or lengths of strip between consecutive weakened lines 14 forms inscription receiving areas which may be provided with one or more blank forms 15 for facilitating inscription entry and these spaces or lengths may be termed form leaves or pad leaves. Aligning apertures 16 are formed in the strips, being preferably arranged in two longitudinal series spaced apart longitudinally of the strip and parallel with eachother and preferably arranged so that one aperture of each series is positioned toward the forward end of each form leaf. 'lhese apertures are utilized in the record machine for controlling strip feed for aligning the blank forms with each other and with the writing platen and also, by cooperation with a mechanism forming an important part of this invention, for folding the strip into the storage compartment 13.

As clearly shown in Fig. 2, the feeding and folding mechanism may be located adjacent to an intermediate p'artition'17 dividing the supply compartment from the filing compartment and partially overlying the latter. The main feed shaft 18, disposed transversely of the machine, is mounted in bearings carr1ed by the frame and an exterior operatin handle 19 is attached thereto and positioned to contact with a spring projected retractible v end of each feeding cycle.

Spaced circular feed discs 21 are rigidly mounted upon the shaft 18 for rotation therewith having strip engaging peripheral sur-' faces lying in juxtaposition to the surface of a feed roll 22 rotatably mounted in a carrier or housing 23 and spring pressed by means of springs 2& into cooperative relation with the'feed discs. This carrier is preferably mounted on supporting arms 25 pivoted to the machine whereby the carrier with the feed roll may be swung to or from cooperative relation with the feed discs. The carrier may be held in operative position by means of a releasable latching mechanism 26, and when in such position it will be seen that the-roll provides a feeding grip with each feed disc for gripping the strips for forward feeding thereof.

Each of the feed discs is provided with peripheriallyarranged feed or starting lugs 27 having strip gripping surfaces substantially in extension of the feed surfaces of the feed discs, but laterally disaligned or olfset therefrom, so as to engage the record strips at points thereon laterally disaligned from the feed controlling apertures, it being understood that the feed discs are normally spaced apart so that the feeding grips thereof are respectively aligned withthe series of feed controlling apertures.

Each disc is also formed with a tubular enlargement or hearing 28, which may as shown be integral with the disc and positioned adjacent to the starting lug 27 and extending inwardly from the periphery of the disc. Mounted within this tubular bearing 28 is an extensible and retractible member or folding finger 29 shown in the form of a pin urged toward extended position by means of a spring 30. A lug 31 mounted upon the folding finger 29 extends through a slot in the strip feeding and folding mechanism.

Driving connections between the feed shaft 18 and the feed roll 22 may be provided in the form of a gear 34 carried by said shaft and a pinion 35 carried by the roll shaft and meshing with the gear 34 when the roll is in operative position. A pawl 36 is provided for engagement with the teeth of the gear 34 to prevent retrograde movement of the feed shaft, this pawl being shown as pivotally carried by a transverse rod 37 mounted in the machine casing.

Operatingcam discs38 are mounted upon the feed shaft 18 for sliding movement longitudinally thereof,.-each disc being provided for this purpose with a hub 39 bored to re.- ceive the shaft. These cams are of similar construction, one for use at the right and the other at the left, and a detaileddescription of one will be sufiicient.

Each cam disc 38 has a substantially circular peripheral cam face 40 and a laterally disposed cam face 41 which for a part of its area forms substantially an extension of the cam face 40 but also has a contact surface 42 leading inwardly of the cam disc from the per-ipheral surface thereof. The cam face-42 and the opposite terminal of the surface 41 are angularly spaced apart a considerable distance, the purpose of which will later appear. The operating lug or pin 33 of the operating lever 32 is positioned for cooperation with the cam faces of the cam disc, engaging different faces thereof dependent upon the rotative and lateral positions of the cam disc. Although each of the cam discs 38 is mounted for free sliding movement on the main feed shaft 18 it is anchored to restrain rotary mo tion with said shaft by means of an anchor rod 43 extending parallel to the feed shaft and engaging the cam disc in an aperture therein in such a manner as not to obstruct the lateral sliding movement of the cam disc. Each anchor may be appropriately supported as by means of a supporting hub 44 detachably attached to the supporting bar 37. Each cam disc is positioned adjacent to one of the feed discs 21 and is normally urged away from the same by means of a centrally arranged coiled compression spring 45 which may surround the feed shaft and be compressed between the adjacent faces of the cam disc and feed disc.

Automatic cam controlling mechanism, controlled by operation of the feed mechanism, is provided to adjust the cam discs 38 in one direction,"adjustmentbeing efi'ected in the opposite dirt tion by means of the springs 45. As shown in the illustrative embodiment, this mechanism includes a carrier or support 46 in the form of a disc secured to the feed shaft 18 through an apertured hub and a set screw whereby the carrier rotates with the feed shaft and feed discs. A cam shifter is rotatably mounted upon this carrier through a hub or bearing 47 in which a shaft 48 is rotatably mounted and carries a shifter cam 49 secured thereon with its plane extending transversely to the plane of the carrier disc in an opening 50 in the latterand positioned between the adjacent faces of the hubs 39 so as to operatively engage the latter for sliding the cam discs. The shifter cam 49 may be of desired form for controlling shifting of the cam discs in timed relation to the feeding operation, but itis convenient to construct it substantially as shown with flattened cam faces arranged so as to contact with the hub faces in such a manner as to cooperate theremechanism. The cam "as shown is substantially square, having truncated corners so as to form fiat corner cam faces alternating with the flat cam faces formed by the sides of the square. The successive fiat cam faces are thus positioned at different distances from the center of rotation of the cam whereby the cam discs will be moved from one position to another when the shiftercam 49 is rotated to bring consecutivefaces thereof into cooperative relation with the hubs 39.

For rotating the shifter cam 49 step by step, a toothed or star wheel 51 is secured to the shaft 48 and a trip pin or lug-52 is carried by one of the supports 44 and positioned to contact with the teeth of the star wheel as the latter is carried in its orbital movement by operation of the feed shaft.

,In the embodiment shown, the star Wheel is provided with eight teeth cooperating to re tate the shifter cam 49 one-eighth of a complete revolution at each revolution of the 'feed shaft, thus at each step bringing the next successive cam face of cam 49 into cooperative relation With the respective hub 39. It will, therefore, be seen that the cam discs 38 will be forced outwardly by action of shifter cam 49 at each alternate revolution of the feed shaft, and will be positioned inwardly through coaction of the springs 45 at the other alternate revolutions of the feed shaft. It will be observed that the shifter cam 49 will be retained during substantially a complete revolution of the feed shaft, in position to which it has been previously shiftedby the shifting mechanism because of the cooperation of the flattened cam faces with the flat faces of the hubs 39, said cam faces sliding upon the hub faces during this period. 1 v

A strip separator plate 53 may be provided, being positioned at the forward side of the roll carrier 23, and having one edge thereof extending slightly under said carrier, as clearly shown in Fig. 2, and lying substantially in the path of the fed strips as they emerge from thegrip of the feeding mechanism. This separator, preferably in the form of a plate extending transversely of the casing, is suitably attached to the machine frame and carries on its under side one or more brackets 54 having downwardly curved downwardly directed strip guiding surfaces positioned in the vicinity of the feed disk peripheries so as to restrain and gulde the file recordstrip in position close against the disc periphery whereby it may more satisfactorily cooperate with the strip folding mechanism.

plate emerging through an aperture or slot in the forward wall of the roll housing 23. If it is desired to refold or file more than one strip, the desired number of file strips will be positioned beneath the edge of the separator plate 53.

The feeding of the strips forwardly into inscription receiving position is effected, as

understood by those skilled in the art, by the friction grip exerted upon the strips by the feeding mechanism when the feed shaft 18 is rotated in a forward feeding direction. The shaft 18 is checked after one complete revolution by the stop 20, and the circumference of the feed discs 21 is of sufiicient length to feed the strips forwardly a distance greater than the length of the form or pad leaves, that is, the length of strip between consecutive transverse weakened lines 14. However, when the apertures 16 of the several strips come into alignment with the feed grips the feeding pull upon the respective strip is stopped, and the strips are thus all brought into correct registry with each other and in correct alignment over the platen for the reception of an inscription. Just prior to engagement of the handle 19 with stop 20, and after strip alignment has been effected, the starting lugs 27 may move into position to engage the strips out of longitudinal alignment with the feed controlling apertures, thus gripping the strips against the feed roll 22 and jogging them forward slightly. The strips are thus gripped and held in correctly aligned position at the time the feeding operation is checked.

In order to initiate the next feeding cycle the stop lug 20 must be retracted, whereupon the feed shaft 18 may be turned to feed the strips forwardly. The feed control apertures 16 now having passed beyond the feed grips, the strips will be fed forwardly as before.

Assuming a part of the file strip A. which is to be placed at the inner end of the zigzag folded file pad B, is at this time being fed forwardly from the feed grip under the'edge of the separator plate 53, the cam discs 38 will have been shifted by the shifter mechanism above described so as to be urged by their respective springs 45 away from the respective feed discs 21, the lateral faces or sides of the shifter cam 49 being at this time posiduring operation of the machine, the file strip 39. Therefore,the folder finger operating pins or lugs 33 will be positioned relatively to the cam faces 40 so as not to engage the latter but will be in position to engage the cam faces 41. Therefore, when the pins 43 are carried past the terminals of cam faces 41, the restraint exerted upon the folding fingers or pins 29 will be removed and said fingers will be projected outwardly by the compression springs 30 into position to engage in the apertures 16 of the file strip, which at this moment 1 are fed forwardly by the feeding mechanism in position to receive said folding fingers. In other words, the strip feed is synchronized with the aperture-engaging movement or actuation of the folding fingers whereby the latter are positioned to enter the desired apertures. When thus engaged in the apertures 16 the folding fingers are carried forwardly with the feed discs, carrying with them the part of the strip which is to be folded at the inner end of the file pack B as will be clear upon reference to Fig.3, showing the position assumed just prior to strip disengagement by the pins 29. The folding fingers 29 will be retracted by engagement of the lugs 33 with the inclined cam faces 42 at such time as the strip is carried thereby into position for lying in folded position upon the' pad B. The strip falls naturally in folded position upon said pad as soon as the folding fingers 29 are retracted.

Continued rotation of the feed shaft moves the folding fingers to fully retracted position as the pins 33 are carried outwardly as far as the cam surface 40. Then the shifter cam 49 is operated by engagement of the star wheel 51 with its operating lug 52, thus moving the cam discs 38 outwardly so that the cam faces 10 engage and cooperate with the lugs 33 to maintain said folding fingers 29 retracted during the next succeeding rotation or feeding cycle of the'feeding disc. The result of this action is that there is no folding coaction between the folding fingers and the apertures l6 atthis time brought into alignment therewith, and the file strip A therefore is not carried to the inner end of the file pack B, but is projected to the outer end thereof through the forward impulse exerted on the 115 file strip by the feeding mechanism. The fold at this part of the strip thus falls into folded position at the outer end of the refold pack. This phase of folding the file strip may alsmnw be'aided by the folding tendencyengendered by the fold creases of the strip.

At the next succeeding feeding cycle the folding coaction first described is repeated, and the folding operation is thus continued being first moved to fold at one end of the file pad and then at the other, in alternating relation, and the strip is thus laid in a zigzag pad. It will be observed that the control of the tioned so as to engage the end faces of hubs feeding fingers 29 is selective in its action to cooperate in folding relationonly with alternate apertures 16 of each series, folding coaction with the other apertures being auto- 'matica-lly omitted.
